Tango Blast, Texas Syndicate, Barrio Azteca and the Texas Mexican Mafia were listed at the largest and most connected to Mexican drug cartels.

Report Criticized

But one drug war expert is skeptical about the motives and accuracy of the report.

UTB Government Chair Guadalupe Correa-Cabrera said the report contradicts statistics from the FBI and even DPS itself.

Those previous statistics report that crime has fallen in the United States and that border communities are among the safest.

Correa-Cabrera said the report is "political" and "an attempt to gain more federal funds" but can also be seen as a "double-edged" sword.

"If the situation is as alarming as the report states, then that would mean that Texas authorities are as incompetent as Mexican authorities to combat organized crime," Correa-Cabrera said. "Therefore the Texas state would be as failed as the Tamaulipas state. And Mexico (through Mexican-origin) organized crime groups would be re-conquering Texas in the current drug war times."
